CAR-TRUCK.

EPECIFICATION forming part 01 Letters Patent No. 352,535, dated November 16, 1886.

(No model.)

To aZZ whom it may concern:

Be it known that I, AUGUSTUS W. GETOH- ELL, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Car-Trucks and Brakes therefor, of which the following is a specification.

This invention relates to that class of trucks in which rollers are employed for traversing the railway; and it consistsof a peculiar combination and arrangement of the parts which support and carry the rollers, which are carried around in a circular movement, the rollers being brought down successively in the revolutions to bear upon the rails of the roadway and beneath a bearing-beam in the truck, whereby the car is propelled upon the rollers, the object being'to provide a truck for cars which requires only the minimum amount of power for propelling them.

The invention further consists in a peculiar brake mechanism to accompany the said rollertruck, the brakeshoe bearing on the trackrails, instead of the rollers, forstoppin g the car.

The construction and operations of my invention will be fully understood from the subjoined description, when considered in connection with the accompanying drawings, in which- Figure l is a side elevation showing two trucks as they appear beneath a car and accompanied by the brake mechanism. Fig. 2 is a side view of one of the roller-trucks,having the side plate removed to show the location and arrangement of the rollers. Fig. 3 is a vertical section of said roller-truck. Fig. 4 is a detached perspective view of the brake mechanism.

A is a non-rotating axle firmly fixed in hangers Band brackets G, secured to the bottom of the car. The axle is set in blocks a a, which are allowed vertical play in the hangers and brackets, the car-body resting on springs S. Upon the ends of the axle are fixed strong bear-. ing-beams D, they having square mortises fitted onto square'tenons on the axles. These beams, with the axles which support them, are non-rotary.

The rotating parts are as follows: E F are two circular rotating plates arranged to revolve on the axle on each side of the said beam D, the

axle having round portions at each side of the tenon upon which said plates turn. The inner plate bears against a shoulder, e, on the axle. The round portion of theaxle at this point being larger than the square portion enables the plate to be slipped on over the square part in puttingthetruok together. The round portion for the outer plate being smaller than the square, the plates are held on the axle by anut', n, outside of which is placed a block, a, which occupies its place in the slot of the bracket G. The hangers B are located inside of the shoulder 6 on the axle A, and there is placed through the hanger and the block and axle a vertical bolt, I), for the purpose of strengthening the hanger and providing for bracing it, to relieve the truck of the surging of the car sidewise.

Between the rims of the plates B and O are arranged rollers G G, which have journals 9 9 playing in radial slots near the outer circle of the pl atesB C. These rollers have flanges, and run in rapid succession on the track-rails in the manner as follows: As the car is propelled the rollers successively pass between the beams and the irackrails. The car is thus supported upon and rolled along on the rollers. This movement causes the plates carrying the rollers to rotate, and thereby brings the rollersin quick succession between the beams and track-rails. The radial slots are provided for the purposeof giving opportunity for the rollers to run parallel with the track-rails the length of the straight under side portion of the beams, and to prevent great rattling of the rollers or their poundingon the track as they come down thereon a curved shield, H, is provided on each side of the truck, which serves to retain and guide the rollers in their downward move ments onto the track, gradually directing them, so that they strike the track with less force.

The brake mechanism consists of rock-shafts I 1, journaled in hangers J J, and having crankarms K K on each end, which carry brakeshoes L L, designed to bear and drag on the track-rails, thus braking on the track-rails instead of the trucks. To the central part of the rock-shafts are attached levers M, to the upper ends of which are attached cords, which pass over pulleys N, secured midway between the hangers to the under side of the car-body, said cords leading thence to the car-platforms, where they may be attached to and operated by the usual hand-wheel and shaft. Short depending arms 0 O are attached to the rock shafts I,and are connected togetherby a spring, P, the purpose of which is to draw on the shafts for raising the brake-shoes from the tracks when released by the slacking of the cords.

In Fig. 1 one of the brakes is shown as drawn down and bearing on the track, while the other is seen up in its normal position. These brakes operate in front of the truck, and have the whole weight of the car to aid in creating the friction for stopping the car.

Having described my invention, I claim- 1. In a truck for railway-cars, the combination, with a non-rotating axle fixed in suitable hangers and brackets'attached to the carbody and provided with the fixed bearingbeams B, of the circular rotating plates E F, carrying the rollers G G, said rollers being arranged to operate substantially as and for the purpose specified. t
